Now that we have explored the idea to use the Scream4 to create an automatic level envelope, we can apply it for different effects.

Normally we would use the built-in modulator of the PH-90 phaser to get a smooth or swirly phasing effect. But the constant modulation of the built-in LFO can become a bit too repetitive on some tracks.

In this patch we use the automatic envelope to control a Phaser.

The AutoPhaser patch uses 3 phasers so we can have two kinds of operation. In the normal mode the audio signal is routed through 1 phaser. The automatic envelope controls the Frequency of the Phaser so both the left and the right channel are equally affected.

In Stereo Mode (Button 4 on the Combinator) both channels of the audio signal are routed through a separate phaser. The Frequency of the phaser for the right channel is inversely modulated by the automatic envelope. This way the phaser effect is in stereo and can add a nice touch to, for example, an acoustic guitar loop.

Button 4 toggles between normal and stereo mode. It does so by disabling and enabling the corresponding PH-90s.

Rotary 2 controls the amount of the automatic envelope by adjusting the master level of the bottom Micromix.

Rotary 4 controls the pan knobs for the two PH-90s when in stereo mode. This way you can adjust the width of the stereo effect when you use it on a mono source.
